FORCE-'PUM P.

SPECIFICATION forming part of Letters Patent No. 691,654, dated January 21, 1902. Application filed September 20, 1900. Serial No. 30,589.. (No model.)

To all whom it may concern.-

Beit known that I, PHILIP A. MYERS, a citizen of the United States, residing at Ashland, Ohio, have invented certain new and useful Improvements in Force-Pumps, of which the following is a specification.

My invention relates to improvements in double-acting force-pumps; and the object of the invention is to simplify the construction to a great degree and to increase the efficiency and durability and render the valves readily accessible.

I have illustrated the invention in the accom panying drawings, in which-- Figure 1 is a plan view of the pump with the cap removed. Fig. 2 is a similar view with the valve-diaphragm also removed. Fig. 3 is a cross-sectional view of the pump. Fig. 4 is a plan view of the cap, taken from the bottom. Fig. 5 is a longitudinal sectional View taken on the linear 00, Fig. 1, and y y, Fig. 4. Fig. 6 is a longitudinal sectional view of the cap. Fig.7 is a view similar to Fig.1 of a modification, and Fig. Sis a view of the cap used in this form.

In the figures, A represents the body of the pump, which is preferably in the form or shape shown and made by casting in a single piece, it being provided with a suitable base A, designed to be bolted to the floor or any The body Aincludes a horizontal cylinder, which is arranged low down upon or close to the base and contains a piston B of suitable construction. The

ends of the cylinder are closed by heads A and A bolted to the body, and through one of the heads A passes the piston-rod, which is preferably operated by a lever C, having its lower end connected by a link 0' to a projection from the head A An inlet-port D is located on one side of the cylinder, and an outlet-port E is similarly arranged upon the opposite side, these ports being formed by integral flanges projecting from the body of the casting and adapted for feed and delivery pipe connections. The upper portion or side of the body A is made perfectly flat, as indicated at a, to receive the valve plate or disk I, (hereinafter more fully described,) above which is mounted the cap F, secured in place by suitable bolts. From the inletport D passage d extends upward toward each end of the cylinder, terminating in a port d,which is normally closed by a'weighted flap-valve t" and which opens automatically upward on the suction-stroke of the piston to permit the water to pass from the inlet-port upward into the space or compartment 100- tween the cap and the valve. In close proximity to the port (1 and valve 7) is a port (1*, leading down into the interior of I the cylinder at each end, the valve plate or disk being.

cutaway, as shown, to provide an opening corresponding to this port. The cap has a division web or rib f, which rests against the valve-disk and divides the space above the same into three chambers f, f and f the inlet ports and valves just described opening, respectively, into chambers f and f*. The third compartment f is in communication by two ports or passages d with the opposite ends of the cylinder, flap-valves i similar to those already described, closing these ports. This chamber also communicates by a port d with the outlet-port E of the body and is also in communication with the airchamber.

The arrangement being such as described, the operation of the pump will be clear, but may be briefly described as follows: Supposing the piston to be moving from right to left, the suction created behind the piston would cause valve-z" to lift and the water to pass by ports or passages d and d to the space behind the piston. Simultaneously the waterin front of the piston would be forced through the passages or ports (1 into the chamber or compartment f and thence through port or passage cl to the delivery-port.

In the modified form the air-chamber is dispensed with, as is also the outlet-passage d and the outlet is directly from the top of the cap, as shown at (F, the action in other respects being substantially the same.

In order to drain the cylinder of any sediment which may accumulate therein, open- The valve-disk is simply a sheet of leather or the like cut to the shape shown, the valves formed by the circular tongues being weighted by suitable flat metal plates, as indicated. By this form of valve-disk the valves are all assembled, so that by removing the cap they are all exposed to view, and they may be easily renewed when worn or damaged.

It will be understood that while I have shown the valves as circular Weighted tongues carried by a single valve disk or sheet and prefer this form, I may use any ordinaryand well-known form of valve, if desired.

Having thus described my invention, what I claim is 1. In a force-pump, a single horizontallydisposed cylinder having a piston therein, said cylinder having a thickened upper Wall with a flat face, a cap having integral webs coacting with said fiat face to form a double and two single valve-chambers, an inlet-port formed in the side of said cylinder and having branch ports leading to said single valvechambers, valves controlling said ports, passages in the body of the cylinder leading from said single chambers to opposite ends of the cylinder, ports in the body of the cylinder leading from the ends of the cylinder to the double chamber with valves controlling said ports, and a water-outlet from said double chamber, substantially as described.

2. In a force-pump, a single horizontallydisposed cylinder having a piston therein, said cylinder having a fiat upper face, a cap having integral webs coacting with said flat upper face to form a double and two single valve-chambers, branch ports in the body of said cylinder leading to said single valvechambers, valves controlling said ports, an inlet-porti'or supplying Water to said branch ports, passages in the body of thecylinder leading from said single chambers to opposite ends of the cylinder, ports in the body of said cylinder leading from the ends of the cylinder to the double chamber, and a Wateroutlet from said double chamber, substantially as described.

3. In a force-pump, a single horizontallydisposed cylinder having a piston therein, said cylinder having an upper Wall with a fiat face,a cap having integral webs coacting wit-l1 said flat face to form a double and two single valve-chambers, an inlet-port formed in said cylinder and having branch ports leading to said single valve-chambers, valves controlling said ports, passages in the body of the cylinder leading from said single chambers to opposite ends of the cylinder, ports in the body of the cylinder leading from the ends of the cylinder to the double chamber with valves controlling said ports, a compressedair chamber carried by said cap having its interior in communication with said double chamber, and a water-outlet from said double chamber, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

PHILIP A. MYERS.
